CDP Data Ownership & Portability Toolkit: Migration Cost Calculator + Vendor Questions (Data.C2)

Stop Guessing What Happens When You Want to Move From Packaged CDP to Warehourse-native Solution

Most vendors say “you own your data.” Few make it true in practice.

The Data Ownership & Portability Toolkit is the practical evaluation toolkit that helps marketing, data, and architecture leaders:

  • Understand true data ownership and portability risks
  • Quantify the real cost of migrating away from a packaged CDP
  • Ask the right questions to get written proof from vendors (not sales promises)
  • Score packaged vs. warehouse-native (composable) architectures objectively

Who Is This For

  • High-growth startups and mid-sized  brands with 50-200K+ customer profiles evaluating or reconsidering their CDP
  • Marketing Ops / RevOps leaders tired of vendor lock-in
  • Data teams preparing for a platform switch or composable CDP move
  • Consultants and agencies advising on customer data architecture

What Is Inside

1. Data.C2 Workbook (PDF) A structured 20+ page framework that walks you through:

  • Defining your actual ownership and portability requirements
  • What “good” vs. “poor” architecture looks like
  • Step-by-step due diligence process
  • Objective scoring for both packaged CDP and warehouse-native options

2. Migration Cost Calculator (Excel) Ready-to-use model with:

  • Pre-built component hours for a medium-sized company (250K profiles, 2 years history, 4 destinations)
  • Roles & hourly rates (Project Lead, Data Engineer, CDP Spec, DevOps)
  • Six workstreams: Extraction, Schema Transformation, Identity Reconstruction, Activation Rebuild, Validation & Testing, Project Management
  • Automatic cost ranges + 30% contingency

3. Vendor Information Request Pack Targeted question lists you can send to vendors:

  • Packaged CDP Vendor Questions (Contractual ownership, export reality, migration mechanics)
  • Warehouse-Native Tool Questions (Identity resolution, Reverse ETL, Audience Builder, Warehouse)

4. Migration Cost Sizing Guide Learn exactly how to size your project (Small / Medium / Large) across every component so you can adjust the calculator for your specific data volume and complexity.
